My opinion is the opinion I hold right now. Even the facts I believe I know, might be wrong. Correct me politely and I'll look it up and grow from our interaction..
As far as I can tell no one person knows everything, and I am no exception. However, if you are rude I'll try to get past it to see what you're saying, but in general, I'll just move on.
I will try to respect everyone I meet, as best I know how. Please let me know if I don't do so, I'll try to get better at it.
